UNITED STATES PATENT OF ICE.

CHARLES A. ENSIGN, OF NAUGATUCK, CONNECTICUT.

MACHINE FOR MAKING CORDED BINDING FOR INDIA-RUBBER AND OTHER FABRICS.

Specification forming part of Letters Patent No. 56,393, dated July 17,1866.

To all whom it may concern:

Be it known thatl, CHARLES A. ENSIGN, of Nan gat-uck, county of NewHaven, and State of Connecticut, have invented certain new and usefulImprovements in Machines for Making Binding for India-Rubber or otherFabric; and I do hereby declare that the same is described-andrepresented in the following specification and drawings, so as to enableothers skilled in the art to make and use the same therefrom.

Letters marked thereon indicate like parts in each of the figures.

The nature of this improvement consists in making a machine automatic inits operation, so that by introducing the material into one part of themachine it will be delivered therefrom in readiness for use.

In the accompanying drawings, Figure 1 is a sectional side elevation.Fig. 2 is an end elevation. Fig. 3 is a top view.

ais the frame-work of the machine. I) b b b are rolls fitted intobearings formed in the frame-work in the usual way, between which thematerial passes onits introduction into the machine. The rolls 1) and bhave one or more depressions, 0, formed in the surface thereof. b hasone or more projections, c, which are fitted into the depressions so asto correspond in shape with the shape of said depressions. b is a rollhaving a V-shaped depression, which is so made or arranged as to guidethe cord (1- from the spool e to the center of the fabric into which itis to be closed while passing through the machine.

ff are rolls fitted in bearings in a yielding or adjustable manner inthe frame a by means of elastic pads g or set-screws h, (one or both, asdesirable.) The lower roll, f, is provided with a depression about thesize of the cord d, so that as the fabric passes from the rolls b 1) bwith the cord d lying on the upper side and in the center thereof, theupper roll, f, will press the cord with the fabric into said depressionformed inthe bottom roll, f.

t'is another roll just forward of the latter, having a groove madeV-shaped, the bottom of which is about the width of two thicknesses ofthe fabric and the diameter of the cord (1, and about the depth of halfthe width of the fabric.

43 is a wheel arranged on a shaft having its bearings also in theframe-work a. Said wheel is made about the thickness of the diameter ofthe cord d, and having a circular groove in its edge, so that as thefabric passes forward from the rolls f the wheel t" will press the cordwith the fabric into the depression of the roll 2', the object of which(the roll z' and wheel t") is to turn up the'edges of the fabric andhold the cord (1 in its angle in readiness to be pressed together,thereby inclosing the cord d in the center or angle of the fabric, whichthence passes between two perpendicular pressrolls, 70, having eachcircular grooves about the shape of a half-circle to receive thecord-enlargement and press the folds or two parts of the fabrictogether. These two rolls It are arranged in a perpendicular position inthe projecting ends of properly-formed arms or springs I, just in frontof which are arranged guideplates is, to guide and aid in closingtogether the edges of the fabric passing from the roll t' and wheel 41.These springs are made in a proper or desired shape and secured in anyproper manner to theframe-work a. From these rolls the fabric passesforward between two horizontal rolls, at. These rolls are also securedin hearings in the frame-work in a yielding or adjustable manner, as therollers f, so as to allow or compensate for any inequality of thethickness of the material, and thus prevent any injury thereto. Thelower roll, a, is provided with a recess about the size and shape of thecord d, so that as the material is passing through these rolls thefolded parts will be closely and firmly pressed together. Each of theserollers have their respective gears for transmitting and equalizingmotion from one to the other through the whole train.

The power by which the machine is operated may be applied by means of abelt to the pulley m in the usual way, or to a pulley which may beplaced on the shaft 0, on which is a gear, 0. The gears 0 0 0, are forthe purpose of transmitting motion from the gear of the roller f to thegear of the roll n.

Thus it will be seen that by setting the machine in motion and insertingthe end of the strip of fabric between the rollers b, and also insertingone end of the cord (1 near the center
